Specification of Letters Patent.

- Patented May 26, 1908.

' Application filed September 19, 1907. Serial No. 393,707.

. citizen of the United States, residing at Lewbeing mounted upon-the rear end of-the 'istown, in the county of Fulton, State of Illinois, have invented certain newand useful Improvements in Clod-Crushers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

- This invention relates to new and useful improvements in clod crushers for reducing or pulverizingthe soil of hard. irregular ground and-in its broad conception it comprises. a roller made in se arable sections.

The primary object o the invention is to provide a clod crusher embodying a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description in which reference is-had to the accompanying drawings forming a art of this specification,

like characters of re erence designating similar parts throughout the several I views, Wherein:

Figure 1 is a top plan view of aclod crusher constructed in accordance with the present invention. Fig. 2 is a-front end elevation thereof. Fig. 3 is a side elevation thereof. Fig. 4 a transverse sectional view through the crushing cylinder, and Fi 5.is a detailed perspective view of one of t e bars of said cylinder, the other bars. being similar in construction. i I

In the accompanying drawings the nu meral 1O designates an openrectangular frame, which carries the forwardly projecttongue. 12. The frame 10 is provided at its ends'with depending bracket'hangers "16 constructed as bearings for a transverse axle 18, the latter 0 ing atitsen'ds wheels .19 prov ded i n the mner'side faces of their with square recesses 20 arranged in annular series to receive the reduced squared ends 21 of closely associated clod cr'ushing bars 22. The bars 22 are of triangular shape incross section and present their apices to the ground. Two annular series of such bars are employed, the bars of each series having their outerends enga ed in the recesses 20 of the res ective whee s 19. The inner ends 21 of the are 22 are on aged in squared recesses 23 formed in annu ar series in the side faces of a centrally located wheel 24. The membersof each :series of bars 22 are reinforced and connected by annular bands 25 secured to the inner circumferential faces of said bars by rivets 26. It will thus be seen that the bars 22 are detachable from the Wheels 19 and 24 and that b addin or taking awa wheels similar to tiie whee 24, the width 0 the crusher may be increased or decreased as desired, in accordance with "the circumstances of use. The intimate relation and the peculiar shape and arrangement of the bars 22 assures of the soil bein thorou hl'y, uniformly and easily reduce hat is claimed isz In a clod crusher, a crushing cylindercomprising end wheels, each havin a rim r0- vided with an annular series 0 square recesses in its inner face, a wheel intermediate the end wheels and having a rim provided with annular series of squared recesses in opposite sides thereof, two annular series of crushing bars, each barbeing oftriangular shape m cross section andhavin'g op osite' to the squared recesses and detacha ly fitted therein, and annular-bands supporting the crusher bars between the end and intermediatewhe'cls.
